The DM-TX-4KZ-202-C provides a versatile interface for ultra high-definition AV and computer sources as part of a complete Crestron® DigitalMedia™ system. It functions as a DM 8G+® transmitter and switcher with two HDMI® inputs. It also functions as a control module, providing RS-232 and IR control ports, plus Ethernet and USB HID ports for a total connectivity solution.
Its low-profile, surface-mountable design makes the DM-TX-4KZ-202-C ideal for installation beneath a conference table, inside a lectern or equipment rack, or at virtually any other location in a boardroom, classroom, auditorium, or residence. It connects to the head end or display location using a single CAT type twisted pair cable. In addition to DM 8G+, it is also compatible with HDBaseT®, which allows it to be connected directly to the input of an HDBaseT certified display device.
4K60 4:4:4 & HDR Support
Crestron DigitalMedia (DM®) was the world’s first AV signal distribution solution to deliver end-to-end 4K signal management for large-scale commercial and residential applications. DM “4KZ” endpoints and cards enable new and existing DM systems to handle full 4K60 4:4:4 video signals, as well as HDR video signals (HDR10), without having to replace any wiring or switchers. Any Crestron DM system that supports 4K can be upgraded to handle 4K60 4:4:4 and HDR by simply installing DM 4KZ based transmitters, receivers, and I/O cards.
DM 4KZ technology employs VESA® Display Stream Compression (DSC) to enhance the capabilities of DigitalMedia to handle the extreme bandwidth requirement of resolutions beyond 4K30 4:4:4 and 4K60 4:2:0. DSC is a lightweight, line-based 2:1 compression standard that delivers visually lossless performance for 4K60 4:4:4 and HDR signals. DSC is applied only to 4K60 4:4:4 and HDR input signals. All other signals are transported uncompressed.
Engineered for ultra high-bandwidth and ultimate scalability, DigitalMedia 8G+ (DM 8G+) provides a true one-wire lossless transport for moving high-definition video, audio, power, Ethernet, and control signals over twisted pair copper wire. DM 8G+ transports uncompressed Full HD 1080p, WUXGA, and 2K signals over distances up to 330 feet (100 m) using Crestron DM Ultra Cable, Crestron DM 8G® Cable, or third-party CAT5e. Higher resolution signals up to UHD and 4K are supported over distances up to 330 feet (100 m) using DM Ultra Cable, 230 feet (70 m) using DM 8G Cable, or 165 feet (50 m) using CAT5e.
Crestron DigitalMedia 8G+ technology is designed using HDBaseT Alliance specifications, ensuring interoperability with other HDBaseT certified products. Via its DM 8G+ output, the DM-TX-4KZ-202-C can be connected directly to an HDBaseT compliant device without requiring a DM receiver.
Multimedia Computer/AV Interface
The DM-TX-4KZ-202-C provides simple switching between two HDMI inputs. Both inputs support resolutions up to UHD and DCI 4K, and can also handle DVI and Dual-Mode DisplayPort signals using an appropriate adapter or interface cable. The inputs can be switched automatically for plug-and-play simplicity, or programmatically through a Crestron control system.
A single CAT type cable connects the DM-TX-4KZ-202-C to a DM switcher or receiver, or to an HDBaseT device, transporting video, audio, control, networking, and power signals all through one simple RJ45 connection.[1,4,5] Multiple DM-TX-4KZ-202-Cs may be installed and connected to a single DM-MD series switcher to provide input connectivity and signal routing for multiple sources at different locations throughout a room or facility. Or, a single DM-TX-4KZ-202-C can be fed straight to a single DM 8G+ receiver, affording a simple solution for extending a computer or AV signal to a single display.
Local HDMI Output
An HDMI output is included to enable pass-through of the selected input signal to feed a local display, monitor, or sound system.
Along with high-definition AV and control, DigitalMedia also integrates high-speed Ethernet networking for a total signal distribution solution. The DM-TX-4KZ-202-C includes a 10/100 Ethernet port, which can be used to provide a convenient LAN connection for a local network device.
Embedded Device Control
The DM-TX-4KZ-202-C includes built-in IR, RS-232, and Ethernet control ports to enable programmable control of the devices connected to it (via a control system). It also offers an alternative to such conventional control methods by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to the control system, the DM-TX-4KZ-202-C provides a gateway for controlling the connected source devices right through their HDMI connections, potentially eliminating the need for any dedicated control wires or IR emitters.
USB Signal Extension
The DM-TX-4KZ-202-C functions as a versatile USB keyboard/mouse extender with both host and device ports provided onboard. This allows a computer (or other USB HID-compliant host) to be connected to the DM-TX-4KZ-202-C and controlled remotely by a USB HID keyboard and/or mouse located elsewhere. Alternately, the keyboard/mouse may be connected locally and used to control a remote computer. Routing of the USB HID signals is handled through the DigitalMedia system. Support for other types of USB devices can be enabled using Crestron USB over Ethernet Extenders (model USB-EXT-DM-LOCAL and USB-EXT-DM-REMOTE).
Crestron Connect It™
A Crestron Connect It Cable Caddy (TT-100 or TT2-100 series) offers a convenient tabletop connectivity solution that works seamlessly with the DM-TX-4KZ-202-C. The cable caddy gets its power and control from the DM-TX-4KZ-202-C through a simple USB connection.
Compact and Versatile
The DM-TX-4KZ-202-C is designed to be mounted to a flat surface or placed on a shelf. It is compact enough to fit discreetly inside a presentation lectern or beneath a table, and can even be attached to a rack rail in the back of an equipment cabinet. It can be powered using the wall mount power pack (included), or PoDM+ (Power over DigitalMedia Plus) for a true one-wire solution.[4,5] All connections and LED indicators are positioned on the sides, ensuring optimal access and visibility for a clean, serviceable installation. An array of indicators is provided for easy setup and troubleshooting.
